Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
1. Do not operate this machine before the TRAK K Mill Installation, Maintenance,
Service and Parts List Manual, and ProtoTRAK SMX Programming, Operating &
Care Manual have been studied and understood.
2. Do not run this machine without knowing the function of every control key, button, knob,
or handle. Ask your supervisor or a qualified instructor for help when needed.
3. Protect your eyes. Wear approved safety glasses (with side shields) at all times.
4. Don't get caught in moving parts. Before operating this machine remove all jewelry
including watches and rings, neckties, and any loose-fitting clothing.
5. Keep your hair away from moving parts. Wear adequate safety headgear.
6. Protect your feet. Wear safety shoes with oil-resistant, anti-skid soles, and steel toes.
7. Take off gloves before you start the machine. Gloves are easily caught in moving parts.
8. Remove all tools (wrenches, chuck keys, etc.) from the machine before you start. Loose
items can become dangerous flying projectiles.
9. Never operate a milling machine after consuming alcoholic beverages, or taking strong
medication, or while using non-prescription drugs.
10. Protect your hands. Stop the machine spindle and ensure that the CNC control is in the
stop mode:
• Before changing tools
• Before changing parts
• Before you clear away the chips, oil or coolant. Always use a chip scraper or brush
• Before you make an adjustment to the part, fixture, coolant nozzle or take
measurements
• Before you open safeguards (protective shields, etc.). Never reach for the part,
tool, or fixture around a safeguard.
11. Protect your eyes and the machine as well. Don't use compressed air to remove the
chips or clean the machine.
12. Disconnect power to the machine before you change belts, pulley, and gears.
13. Keep work areas well lighted. Ask for additional light if needed.
14. Do not lean on the machine while it is running.
15. Prevent slippage. Keep the work area dry and clean. Remove the chips, oil, coolant and
obstacles of any kind around the machine.
16. Avoid getting pinched in places where the table, saddle or spindle head create "pinch
points" while in motion.
17. Securely clamp and properly locate the workpiece in the vise, on the table, or in the
fixture. Use stop blocks to prevent objects from flying loose. Use proper holding
clamping attachments and position them clear of the tool path.

Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
18. Use correct cutting parameters (speed, feed, depth, and width of cut) in order to prevent
tool breakage.
19. Use proper cutting tools for the job. Pay attention to the rotation of the spindle: Left
hand tool for counterclockwise rotation of spindle, and right hand tool for clockwise
rotation of spindle.
20. After an emergency stop, always turn the FORWARD/REVERSE switch to "Off" (STOP)
before releasing or resetting the E-Stop.
21. Prevent damage to the workpiece or the cutting tool. Never start the machine (including
the rotation of the spindle) if the tool is in contact with the part.
22. Check the direction (+ or -) of movement of the table, saddle, and quill when using the
jog or power feed or ram out.
23. Don't use dull or damaged cutting tools. They break easily and become airborne.
Inspect the sharpness of the edges, and the integrity of cutting tools and their holders.
Use proper length for the tool.
24. Large overhang on cutting tools when not required result in accidents and damaged
parts.
25. Handwheels must have the crank folded inside when using CNC programmed machining
or rapid feeds, power feed or jog.
26. Prevent fires. When machining certain materials (magnesium, etc.) the chips and dust
are highly flammable. Obtain special instruction from you supervisor before machining
these materials. Keep flammable materials and fluids away from the machine and hot,
flying chips.
27. Changing the speed of rotation of the spindle must be done while the rotation is on. It is
recommended to stop and start the spindle at a low rate of speed.
28. For non-spindle control machines - interlocked table guards. Interlocked table guards
may be purchased from Southwestern Industries, Inc. if deemed necessary by the user.

Electrical Connection
The TRAK K2, K3 & K4 Knee Mills can be configured for 220 or 440 volt 3 phase electricity.
These machines also require a 110V power source to power the control. NOTE: Machines
with Optional Spindle Control is only available in 220 V configurations.
DANGER!
Be certain that 200-volt electricity (typical range 208 – 240V) is used only with a machine labeled
220 volts at the motor and at the electrics box on the back of the column.
Be certain that 400-volt electricity (typical range 415 - 460V) is used only with a machine labeled
440 volts at the motor and at the electrics box on the back of the column.
DANGER!
The 220 or 440-volt line must originate from a dedicated and independent fused box with a
manual shut-off lever. It is the responsibility of the purchaser to supply a wired box that meets
all local codes and regulations.
Incoming 220 or 440-volt power connects to the machine through the electrical box located on
the back of the column. The power cable enters the black box through a hole on the top of the
box.
DANGER!
Only a qualified electrician should wire the 220 or 440-volt 3-phase electricity.
To convert a K2 or K3 machine from 220 to 440 volt power or vice versa 3 things must happen:
spindle motor must be rewired, overload relay must be set to 8.5 amps for 220 V and 4.25 for
440 volts and the voltage stickers on the electric’s box must be replaced.
To convert a K4 machine from 220 to 440 volt power 3 things must happen: spindle motor must
be rewired, overload relay must be replaced and set to 14 amps for 220 V and 7 for 440 volts
and the voltage stickers on the electric’s box must be replaced.
NOTE: Voltage conversion from 220V to 440V not applicable to machine fitted with
the Spindle Control Option.
See Section 5.1.12 for a diagram of how to rewire the spindle motor.
Southwestern Industries recommends the machine be earth grounded by driving a copper rod
into the ground. It is the responsibility of the customer to install this rod.

Phase Converters
2.11.2
Flange Disconnect/Transformer (Optional)
For those machines that will be run with a phase converter it is recommended that it is a rotary
type rather than a static phase converters. Rotary phase converters allow for varying loads in
the system. The electrical load on the machine will vary based on the type of cut taken. Static
phase converters can only be used on machines with a non-varying load. The phase converter
for the K mill machines must be rated at a minimum of 5 KVA for the K2 and K3 and 7 KVA for
K4.
The Flange Disconnect Option eliminates the need for the user to provide a power disconnect
for the machine on their own, while the Transformer Option allows the user to provide one
power source to the machine. Note: This option is not available to machine fitted with
the Spindle Control Option.

2.12 Air Connection - Optional
The K mill machines have an air hookup in the rear of the machine if the machine has a power
drawbar or auxiliary function option. Auxiliary function options are only found on 3 axis mills.
If the machine has a power drawbar option then the machine will include an air regulator, air
manifold and an oiler. The air fitting is ¼” NPT. Within the manifold there is an additional air
line port in case the user wants to hook up an air line to clean chips. Remove the plug to gain
access to this port. If the machine has an auxiliary function option then the machine will include
an air solenoid as shown below.
The air regulator is set to 90 psi at the factory for the power drawbar unit and solenoid. See
Section 5 for more information on the power drawbar unit. The air comes in through the
manifold, and then into the air regulator that tees off into an oiler for the power drawbar unit
and into an air solenoid. The solenoid is used for a misting system the user may install later on
this machine. There is a ¼” quick disconnect air fitting on the solenoid where the mister air
hose can be plugged into. See the figure below for an illustration.

2.13 Mounting the Display Pendant
The ProtoTRAK SMX display pendant mounts to the pendant arm with four 1/4-20 x ¾ SHCS
that are shipped screwed into the left side of the display. There is a locating screw on the
pendant arm to help align the pendant with the mounting holes.
CAUTION!
The locating screw in the arm is used for positioning. Keep a hold of the pendant until the
screws are fastened.
If the pendant arm rotates too freely, remove the painted cap on the bracket attached to the
column and tighten the hex nut to adjust it. Replace the cap.
2.14 Cable Interconnections
All cable interconnections are made at the factory except for those connecting to the pendant
display. There are a total of 4 cables that need to be connected to the pendant for non-spindle
control machines. See Figure 15 & 16 for a complete illustration of cable interconnections for all
components. There are an additional 2 cables for the electronic handwheel option and 2 more
cables for the spindle control option (digital I/O and spindle control ports).
With the main power to the machine turned off, plug in the connectors that are bundled on the
pendant arm. Each cable mates to only one connector on the pendant display back panel. Use
the key on the pendant to match up the connectors with the correct port. The machine ID port
(or called LPT) and parallel port (hardware key) will have a key plugged into it. The monitor
port and network ports will be left empty during installation.
Make sure there is sufficient slack in the cables for when the pendant is rotated about the
pendant arm. The worst case is when the pendant is all the way forward toward the operator.
The following drawing describes all of the cable connections to the pendant.
Make sure there is a hardware (option) key plugged into the parallel port of the pendant. This
key activates any converters or options ordered. The part # for this key is 22648. The key
must be programmed according to the type of machine it is on and the options ordered.
26
Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
Make sure the machine ID key is plugged into the machine or it will not run. Note: Spindle
control machines use a different machine ID key then non-spindle control machines.
Whenever you replace a cable or reroute a cable it is very important to keep the power cables
and logic cables separated from each other. The power cables consist of the (3) 110-volt motor
cables and (2) 110-volt power cables for the pendant, and a coolant pump or solenoid power
cable. The logic cables are used to carry encoder signals between the cable breakout box and
computer module. Mixing of the power and logic cables may cause noise from the power cables
to interrupt the signals in the logic cables. This can lead to intermittent axis faults or
repeatability problems. See Figure 15 and 16 for a layout of the cable connections.
CAUTION!
Make sure the main power is turned off on the back of the electrical cabinet before plugging in
the cables.

Lubrication
CAUTION!
Failure to properly lubricate the mill will result in the premature failure of bearings, sliding
surfaces & ballscrews
2.15.1 Manual Lubrication
The TRAK mill X & Y way surfaces and ball screws need to be manually lubricated. The
Manual Lube automatically discharges about 4ml of oil
every plunge.
1. At the beginning of each day, manually pull the pump handle.
Note: If the machine has been sitting for a long while, run the machine through the full length of
its travel to ensure lubrication reaches all surfaces.
2. At the beginning of each day, check the oil level in the system. If low, fill with Mobil
Vactra Oil No. 2 or equivalent.
CAUTION!
Failure to manually activate the pump at the beginning of each day and allowing the pump to run
dry may cause severe damage to the TRAK mill way surfaces and ball screws.

Troubleshooting by Symptom
Use this section to begin the process of resolving a service problem. Each symptom type is
described in a few words and then more fully described in an explanatory paragraph. Following
this is a chart that directs in the most logical steps
3.1 Problems Relating to Machining Results
3.1.1 Poor Finish
The part finish is marred with scallops or is very rough.
Do the following Service Codes and document values:
•
Code 33 Software Identification. This is needed if you call SWI Customer Service.
•
Code 11 Measures backlash in the system (Only used on Dual Feedback systems)
•
Code 12 Feed Forward Constant
•
Code 127 Measures backlash in the system (for Z-axis on three-axis systems; not
used on Dual Feedback systems,)
•
Code 128 Enter backlash compensation (for Z-axis on three-axis systems; not used
on Dual Feedback systems)
Possible Cause
Too much backlash entered for code
128 or calculated with code 11.
Machine Tool & Setup problem
Table, Saddle, or Knee Locks are locked
Inadequate or no Lubrication to
Ballscrews and Way surfaces
X, Y, and knee Gibs are not adjusted
properly
X & Y-axis Drive Trains are loose
Way surfaces are pocked, scarred, or
excessively worn
Check This
Verify nothing is mechanically loose and the backlash
values are not higher than what physically is in the
system.
Check for any looseness in the setup (Tool, Tool holder,
Part, Vise, or Fixture). Check the condition and type of
cutter being used, type of material, RPM and Feedrate,
etc. See Machine Tool & Setup Section 4.1
Make sure the Table and Saddle Locks are unlocked.
Never use gib locks with a CNC machine.
Make sure all the Way surfaces are getting proper
lubrication. If not, check to make sure that the lube pump
is functioning properly. Also check for any pinched or
blocked oil lines. See Lubrication Section 4.1.3
Check the adjustment of the X and Y gibs. See X and Y
Gib Adjustments in Section 5.2.1.
Check Repeatability using the Repeatability and Positional
Accuracy procedure. Step by step, carefully inspect the
Drive Train for any looseness. It may be necessary to
disassemble and then reassemble the Drive Train. See
Mechanical Drive Train (X, Y) Section 4.2
Visually check the condition of all the Way surfaces. For
machines that may have excessively worn Way surfaces
you may need to adjust the Gibs in this area. This will
affect performance when using the machine outside of
this area. Check lubrication to affected areas.

ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
3.1.2 Circles Out of Round
Circles are not round within 0.002” TIR over 3.0” DIA. This is best measured by placing
a dial indicator in the quill and sweeping around the part.
Note: The typical slideway-milling machine is not capable of achieving more precise results
although careful adjustments to a new milling machine may produce better results. If more
precise circles are required, then it is recommended to use a precision boring head/boring bar.
Do the following Service Codes and document values:
•
Code 33 Software Identification. This is needed if you call SWI Customer Service.
•
Code 11 Measures backlash in the system (Only used on Dual Feedback systems)
•
Code 12 Feed Forward Constant.
•
Code 127 Measures backlash in the system (not used on Dual Feedback systems).
•
Code 128 Enter backlash compensation.
Possible Cause
Torque values on X and Y-axis are too
high.
Machine Tool and Setup problem
Machine not level
Head is not Trammed
X and Y Gibs are not adjusted properly
Calibration or Backlash problem
TRAK Sensor or Glass Scale problem
X & Y-axis Drive Trains are loose
Head Bolts are loose
Check This
Make sure torque is lower than 20 in-lbs. Normal values for a
machine that is aligned and adjusted properly should be
between 10 and 15 in-lbs. Make sure torque is consistent across
axis travel.
Check for any looseness in the setup (Tool, Tool holder, Part,
Vise, or Fixture). See Machine Tool & Setup - Section 4.1
Verify that the machine is level to specification.
Verify that the Head is Trammed to specification. See Tramming
the Head Sec 5.2.3
Check the adjustment of the X and Y Gibs using the X and Y Gib
adjustment procedures.
Recalibrate the machine. Reset the Backlash. Check
Repeatability and Positional Accuracy. See Calibration &
Backlash Constants Section 5.2.2
Make sure that the Sensor or Glass Scale is installed correctly
according to the Sensor or Glass Scale Installation procedures.
Check for any loose brackets or misalignment etc. Also, check to
make sure the Sensor or Glass Scale assemblies are functioning
correctly. See TRAK Sensors or Glass Scales Sections 4.6 & 4.7.
Check Repeatability using the Repeatability and Positional
Accuracy procedure. Step by step, carefully inspect the Drive
Train for any looseness. It may be necessary to disassemble and
then reassemble the Drive Train. See Mechanical Drive Train (X,
Y) Section 4.2
Verify that all the head bolts are tight. 50 lbs.
3.1.3 Taper Cut on a Programmed Straight Line Move
An unwanted tapered cut occurs, when the machine is programmed to move in a straight
line along either the X or Y-axis. The DRO shows motion of a few thousandths of an inch
in the axis that is not supposed to be moving.
39
Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
Explanation: For straight line cuts along the X or Y-axis, the control is designed to lock
the motor of the axis that is not moving. A taper is created when there is play in the
system. The force of the tool shoves the table or saddle out of position.
The system will respond to being pushed out of position by making an adjustment at the
end of the move.
An unwanted tapered cut is the result of looseness in the system.
Do the following Service Codes and document values:
•
Code 33 Software Identification. This is needed if you call SWI Customer Service.
•
Code 11 Measure's the backlash in the system. Only used on machines with Dual
Feedback systems.
•
Code 12 Feed Forward Constant.
•
Code 127 Measure's the backlash in the system. Only used on machines with single
Feedback.
•
Code 128 Enter backlash compensation.
Possible Cause
Machine Tool & Setup problem
X and Y Gibs are loose
X and Y-axis Drive Trains are loose
Check This
Check for any looseness in the setup (Tool, Tool holder, Part,
Vise, or Fixture). See Machine Tool & Setup Section 4.1
Check the adjustment of the X and Y Gibs using the X and Y
Gib adjustment procedures. See Section 5.2.1
Check Repeatability using the Repeatability and Positional
Accuracy procedure. Step by step, carefully inspect the Drive
Train for any looseness. It may be necessary to disassemble
and then reassemble the Drive Train. See Mechanical Drive
Train (X, Y) Section 4.2
3.1.4 Parts Have Incorrect Dimensions
Parts are being machined with dimensions that are different than those programmed.
Typical accuracy expectations should be:
•
Circles: 0.002” TIR over 3.00” DIA
•
Positional Accuracy: +/- 0.0005"
•
Repeatability: 0.0005"
Note: The typical slideway-milling machine is not capable of achieving more precise results.
Although careful adjustments to a new milling machine have produced better results, you should
not expect the same level of accuracy from an older or worn machine.
Furthermore, the system should be expected to repeat within the resolution of the
displayed DRO numbers of 0.0005”.
Do the following Service Code:
•
Code 33 Software Identification. This is needed if you call SWI Customer Service.
•
Code 123 Calibration.
•

Possible Cause
110 V line is not plugged in
Pendant On/Off switch is Off.
Fuse blown in pendant or electrical
cabinet
Flash Drive failure
Computer/Pendant has failed
Check This
Check incoming 110 V power source to black electrical
cabinet
Check the Pendant On/Off switch
Remove fuses and check continuity.
When the Computer Module starts the boot-up
process, look at the 8th line on the Display Screen. If
the Mother Board of the Computer Module is
communicating with the Flash Drive you will see
"Detecting IDE Primary Master…Scan Disk SDCFB-64".
If the Mother Board of the Computer Module is not
communicating with the Flash Drive you will see
"Detecting IDE Primary Master … None".
Also, check the wiring connection between the Flash
Drive and the Mother Board. See Computer/Pendant
diagnostics Section 4.3
See Computer/Pendant diagnostics Section 4.3

3.3.10 Auxiliary Functions Not Working (Option on 3 Axis
Machines Only)
The Auxiliary Functions will not turn on or off at the programmed times. There are 3
Auxiliary Functions:
1. Activates or deactivates a "110VAC Receptacle" typically used for a coolant pump or
solenoid for mister.
2. Sends an electrical signal to rotate the turret on a "Haas Indexer".
3. Turns the "Spindle Off" at the end of a programmed event. (Note: This function is
not available for retrofits.).
In order to run the above auxiliary functions in run mode, the accessory key on the front
of the pendant must be in the AUTO mode. Press and hold to activate AUTO mode.
All of the auxiliary function signals are carried down to the cable breakout box through
umbilical #2. Each function then has its own relay inside this box. If one of these relays
fail then these features will not work.
Do the following service code and procedures:
•
Code 33 Software Identification. This is needed if you call SWI Customer Service.
Possible Cause
Bad 110VAC "Coolant or solenoid"
receptacle fuse
Poor cable connections
Faulty "Indexer" connector
Bad cable breakout box
Check This
Check if the fuse light indicator next to the plug is lit.
Verify that the fuses are good or bad by checking the
resistance of the fuses using an Ohmmeter.
Check all the cable connections on the cable
breakout box, Coolant Pump, and Air Solenoid
(Located on the Air Regulator). In particular, check
umbilical # 2 cable, which carries the auxiliary
function signals.
Check for continuity between pins 3 and 4, when the
output of the Haas Indexer connector is activated.
Check 110 V power coming out of the AC E-stop port
with the E-stop in the out position. This will cause
the spindle to not run.

3.3.11 E-Stop Error
The E-Stop turns the power off to the axis and spindle motors. This is done by stopping
110V power from reaching the cable breakout box through the use of a relay in the
pendant.
Once power reaches the cable breakout box it distributes power to the axis motors,
auxiliary functions and 110V power to the spindle contactor for non-spindle control
machines. If power does not reach the cable breakout box then none of these functions
will work.
Spindle Control Electrical Box
A 5-volt logic signal is sent to the spindle control board, which energizes a relay that
enables the AC drive.
Non Spindle Control Electrical Box
110V Power reaches the electrical box through the AC E-stop cable. It is used to
energize the spindle motor contactor. If this contactor is not energized the spindle will
not turn on. See Figure 19.
If the E-Stop button is depressed, and no message is displayed on the screen, then
either the E-Stop button or the Computer Module is at fault.
Possible Cause
Faulty E-Stop switch
Bad Computer Module
3.3.12
Check This
Check the cable connections from the computer
module to the E-Stop switch. Check the E-Stop switch
for functionality.
Does 110 V power come out of the cable breakout box
power cord on the pendant? If yes, and the screen
has an E-stop message, replace the computer module.
Limit Switch Error - Optional
Limit switches are installed on the table, saddle, and ram to prevent serious damage to
the machine in the event of a crash. In the event a limit switch is triggered, a limit
switch error will appear on the screen.
Critical Error 52: Servo Error
X-axis Limit Switch
Correct the fault condition and continue.
To return the machine to its normal state of operation, perform the following procedure:
1. Use mechanical handwheels on X and Y to move switch off of trigger. For the Z-axis,
manually lift the arm on the trigger to return the limit switch to its normal position.
Then jog the ram up or down as necessary.
2. Press the "Mode" or "Return" key to reset the control
3. Press the "DRO" key to enable the machine to once again jog.

Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
Possible Cause
Limit switch jumpers in cable breakout
box are making poor contact.
Limit Switches are triggered
Poor Limit Switch Cable connection
Limit Switch failure
Try this
Switch 2 limit switch cables on the cable
breakout box.
Check This
Remove and reseat jumpers.
Reset the Limit Switches using the procedures
described above.
Check for any pins that are loose, pushed in, or bent.
Verify that there is a good connection between the
cables on the cable breakout box.
Does the limit switch problem move to the other axis?
If it does then the switch is most likely the problem.
If it stays with the original axis then it could be the
cable breakout box.
3.4 Problem with the Measurements
3.4.1 X, Y and Z-Axis Measurements Do Not Repeat
With a dial indicator mounted to the bottom of the spindle, touch off a fixed surface
either in the X or Y-axis direction and then set the DRO equal to 0. Crank away several
inches and then touch off again at the same place. If the reading has not returned to 0
on the DRO, zero the display and repeat the procedure. If the measurement does not
repeat, you have a repeatability problem that must be resolved.
Test for accumulative error by moving the axis a number of times to see if the error
gradually grows by a small amount. If so, it may be caused by a misaligned sensor or
scale. If the error abruptly changes by a large amount, it may be caused by a bad encoder.
Expected repeatability numbers should be 0.0005” or less.
Do the following service codes and procedures:
•
Code 304 Toggle X sensor/glass scale on/off
•
Code 305 Toggle Y sensor/glass scale on/off
Possible Cause
Machine Tool & Setup problem
X and Y Gibs are loose
TRAK Sensor or Glass Scale problem
Check This
Check for any looseness in the setup (Tool, Tool
holder, Part, Vise, or Fixture). Make sure there is
sufficient contact between the tool holder and the
spindle. See Machine Tool & Setup Section 4.1
Check the adjustment of the X and Y Gibs using the X
and Y Gib adjustment procedures.
Make sure that the Sensor or Glass Scale is installed
correctly according to the Sensor or Glass Scale
Installation procedures. Check for any loose brackets
or misalignment etc. Also, check to make sure the
Sensor or Glass Scale assemblies are functioning
correctly. Use service codes 304 for X and 305 for Y
to turn off the suspect encoder. Does problem still
exist after turning it off?
50
Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
Possible Cause
X and Y-axis Drive Trains are loose
Encoder Disk or Reader Head on motor
are loose
Spindle and/or Quill are loose
Head bolts are loose
Check This
Check Repeatability using the Repeatability and
Positional Accuracy procedure. Step by step, carefully
inspect the Drive Train for any looseness. It may be
necessary to disassemble and then reassemble the
Drive Train. See Mechanical Drive Train (X, Y) Section
4.2
Swap the motor in question with a known good motor.
For example, swap the X-axis motor with the Y-axis
motor. If the symptom stays with the motor in
question, then replace the motor. If not, then the
motor is not at fault and something else is causing the
problem.
Use a Dial Indicator and check for side-to-side
movement between the Spindle and the Head. Next,
check for side-to-side movement between the Quill
and the Head. There should be no more than 0.0003"
of side-to-side movement. Make sure that there is a
few thousandths gap between the Spindle Collar and
the Quill after tightening.
Tighten Ram bolts
3.4.2 X, Y, and Z-Axis Measurements Are Not Accurate
Measurements repeat, but with a dial indicator mounted to the bottom the spindle,
traversing the length of a gage block or some other measurement standard, the
measurement is not accurate.
Possible Cause
The Calibration is incorrect
Do This
Recalibrate the machine.
See Calibration & Backlash Constants
Incorrect backlash values
If the machine does not repeat bi-directionally check
the backlash on the axis in question.
See Section 5.2.2.
3.4.3 The DRO Is Not Counting
The DRO for one axis is not counting when an axis is moved. Often times if this is the
case the axis will fault. See section on faulting.
Do the following Service Codes:
•
Code 33 Software Identification. This is needed if you call SWI Customer Service.
•
Code 100 Axis open loop test. Used to check the maximum feedrate of an axis and
if the encoders are counting.
•
Code 304 & 305 Turns off X and Y sensor or scale.
Possible Cause
Motor Encoder not counting
Glass Scale or Sensor Failure
Computer/Pendant failure
Check This
See Motor diagnostics (not applicable with Glass Scale
option). Single feedback only.
Does axis now count? If so, replace scale or sensor.
See Computer/Pendant diagnostics

3.4.4 X, Y, and Z-Axis DRO Counting in Wrong Direction
The DRO is counting in the wrong direction.
The positive directions for each axis are:
•
X-axis – Table moves to the left.
•
Y-axis – Saddle moves toward the front of the machine.
•
Z-axis – Quill moves up.
Do the following service code and procedures:
•
Code 33 Software Identification. This is needed if you call SWI Customer Service.
•
Code 313 Check the line that specifies the product.
If the product does not match the machine then the machine ID key will need to be replaced.
3.4.5 X, Y, & Z-Axis Electric Handwheels Count in Wrong
Direction
The Electric Handwheels count in the wrong direction.
The positive directions for each Electric Handwheel are:
•
X-axis - Electric Handwheel turns clockwise.
•
Y-axis - Electric Handwheel turns counterclockwise.
Do the following service code and procedures:
•
Code 308 Reverse X-axis Handwheel Direction.
•
Code 309 Reverse Y-axis Handwheel Direction.
3.5 Problems with the Machine Tool
3.5.1 Spindle Stalls or Turns-Off During Machining
During machining, the spindle turns off and loses power. First check incoming voltage
and connections.
Possible Cause
Machine Tool and Setup problem
Drive Belt in the head is slipping
Cut more than the machine is capable
Insufficient voltage, excessive amp load
Check This
Check the type of material being cut, type and size of
cutting tool, RPM, and Feed rate. Also check the
condition of the cutter to verify that the cutter is not
dull. See Machine Tool & Setup Section 4.1
Check the alignment, condition, and tension of the
Drive Belt.
Check width and depth of cut
Check incoming power. Check overload setting.

3.5.1.1
Spindle Stalls or Turns-Off During Machining (For Machine
with the Optional Spindle Control Drive)
During machining, the spindle turns off and loses power. First check incoming voltage
and connections.
Possible Cause
Machine Tool and Setup problem
Drive Belt in the head is slipping
Cut more than the machine is capable
Spindle Drive Thermal Overload Relay
has tripped
Spindle Drive parameters are not
correct
Spindle Run Command not reaching AC
Drive
Check This
Check the type of material being cut, type and size of
cutting tool, RPM, and Feed rate. Also check the
condition of the cutter to verify that the cutter is not
dull. See Machine Tool & Setup Section 4.1
Check the alignment, condition, and tension of the
Drive Belt.
Check width and depth of cut
IOUT - Current Out (located on the Spindle Drive)
cannot exceed 12.75A for K2/K3 and 21A for K4 for
more than a few minutes. When the Overload Relay is
tripped, an "oL1" error occurs shutting off the Spindle
Drive. The harder the Spindle Motor works trying to
make heavy cuts, the more current the Spindle Motor
utilizes. This can be caused by a cut so large that it
exceeds the machine capability, or a problem with the
spindle motor or AC drive.
May need to re-download the Spindle Drive
parameters. Contact Customer Service for assistance.
Verify Spindle Run LED is on Spindle Control Board.
3.5.2 Spindle Motor Hums or Will Not Run
If the spindle will not run, you must ensure that 110V power is reaching the spindle
motor contactors in the electrics box. Check your 110V power across terminals
wire 3 and ground. If power is not reaching the electrical cabinet but is reaching the
cable breakout box, most likely a relay has failed in the cable breakout box. The cable
breakout box will need to be replaced. This relay is in series with the 110V power in the
E-stop circuit. See Section 3.3.11. If power has reached the electrical box, use the
schematic in Section 4.8 to see how the power is routed.
If the spindle motor makes a constant humming noise during operation, check
the 3-phase power to the machine by checking line to line.
Possible Cause
Wrong voltage
Check This
Check the 220V/440V voltage to the machine
Poor wiring connections
Defective cables or poor cable
connections
Spindle Motor is bad
Check all the wiring connections to the electric’s box.
Check all cable connections
Check the resistance of the Spindle Motor windings on the Spindle
Motor between L1 & L2, L2 & L3, and L1 & L3, using an
Ohmmeter. The resistance should range from ".7 to 1.2 Ohm" for

reads "0 Ohms" or "OL", then replace Spindle Motor. Next, check
the resistance between L1 & Ground, L2 & Ground, and L3 &
Ground, using an Ohmmeter. The resistance should read "OL". If
not then replace Spindle Motor.
Check 110 V coming out of the AC e-stop port on the cable
breakout box. Relay failure in cable breakout box. Replace cable
breakout box.
Spindle Motor Hums or Will Not Run (for machine with the
optional Spindle Control Drive)
The spindle motor makes a constant humming noise during operation or will not turn on.
Note: machines can only be wired for 220 volts. 440 volts will ruin electrical components in the
machine. These components will not be covered under warranty.
Possible Cause
Wrong voltage
Poor wiring connections
Improper wiring/jumper configuration
on the Spindle Motor
Spindle Drive may be in "Local Mode"
and cannot be run from the Pendant
Spindle Motor is bad
Spindle Drive contains incorrect
parameters and is not programmed
correctly
Spindle Enable Signal not reaching AC
Drive
Forward/Reverse Switch is bad or
Spindle Control Board
Check This
Check the voltage to the machine before and after the
Spindle Drive with a Voltmeter. Also, check the
voltage to the Spindle Drive (L1, L2, and L3).
Check all the wiring connections to the Spindle Drive
and Spindle Motor. See Electrical Connection
Check to make sure that the Spindle Motor has the
correct wiring/jumper configuration for 220VAC. See
Electrical wiring section.
On the Spindle Drive, push the "DSPL" button until
"LO/RE" lights up. Use the "Up" and "Down" arrow
keys to choose between "Lo"- Local (Run Spindle
Motor from Spindle Drive) or "rE" - Remote (Run
Spindle Motor from the Pendant).
Check the resistance of the Spindle Motor windings on
the Spindle Motor between L1 & L2, L2 & L3, and L1 &
L3, using an Ohmmeter. The resistance should range
from "1.0 Ohms" to "1.5 Ohms" for K2/K3 and “.5
Ohms” to “.9 Ohms” for K4. If the Ohmmeter reads "0
Ohms" or "OL", then replace Spindle Motor. Next,
check the resistance between L1 & Ground, L2 &
Ground, and L3 & Ground, using an Ohmmeter. The
resistance should read "OL". If not then replace
Spindle Motor.
Contact customer service.
Verify LED on Spindle Control Board is on.
Verify Forward or Reverse LED on Spindle Control
Board is lit.
3.5.3 Spindle Runs Backwards
The spindle motor runs in the opposite direction. The spindle will run in opposite
directions from high to low gear.
54
Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
Possible Cause
3-Phase wires backwards
Check This
Need to switch any 2 of the 3 wires either coming into the
machine or motor. Note: For machine fitted with the optional
Spindle Control, switch any 2 of the 3 wires either coming out
of the AC Drive (T1, T2 & T3) or going into the Spindle Motor
(U, V & W). Warning: Be sure to shut off all power to the
machine before attempting to switch any wires.
3.5.4 Head Noise
Head noise pertains to any unusual noises coming from the head under load and no load
situations. Most often head noise will only be noticeable under load situations. It is
important to try to distinguish between problems with components in the head versus
problems caused by the setup or tooling being used on a particular job. Use the table
below to try to pinpoint the possible cause. Also try to pinpoint the noise by seeing if it
exists in high, low or neutral. For example, if the noise is evident in neutral then this
eliminates the spindle bearings.
Non Spindle Control Drive M achines
Possible Cause
Machine setup or tooling problem
Upper spindle bearing is worn out.
Verify nosepiece is tight on bottom
of spindle.
Spindle bearings are worn out
Check This
If the noise is most evident under load (cutting situations)
then it is important to look at setup and tooling being used.
Ask the following questions.
Is the cutter dull? Is the tool loose in the holder? Am I
taking a bigger cut then is possible on the machine? Is the
part moving in the vice? Am I using realistic speeds and
feeds?
Any one of these can have a significant impact.
Remove the upper bearing plate above the spindle. This will
unload the bearing. If the noise goes away then this bearing
should be replaced.
To check if the nosepiece is bottomed out try to insert a piece
of paper in between the nosepiece and the quill. If a piece of
paper does fit then this may be the problem. Before
tightening or loosening the nosepiece make sure to loosen the
setscrew that holds it in place.
This is categorized by a high pitch sound and is most evident
at high RPM’s. It should also cause chatter under load.
Replace the spindle if this is the case. See spindle
replacement in Section 5.

4.1.2 A Special Word About X & Y Gibs
The slideway surfaces are vital to the performance of the bed mill.
Gibs should be:
•
•
•
flat
free of twist
free of burrs
• free of blockages in the oil passages and channels
Defective or scarred gibs must be replaced. Shimming of gibs may not yield acceptable
results.
It is good machining practice to avoid the use of shop air to clean the chips off a machine.
This risks blowing chips into the sliding way surfaces and compromising the performance of
the machine.
Gibs that are not adjusted correctly will affect the performance of the machine. It will lead to
positioning and repeatability problems. The gibs should be adjusted at least twice a year.
See Gib Adjustments Section 5.2.1.
4.1.3 Lubrication
Lubrication is one of the single, most important maintenance issues and plays a key role in
assuring the performance and durability of the Knee mill. At the beginning of each day
manually supply oil to the way surfaces.
Lack of lubrication can lead to a variety of problems with your machine motion due to
increased friction in the sliding ways. This increased friction may lead to part inaccuracies and
decreased life expectancies of your ball screws and way surfaces.
4.1.4 Machining Set-Up
The machining set-up itself is always something that can greatly influence the performance of
the your mill. The following are some things to keep in mind.
Problems With
Feed and Speeds (spindle rpm)
See below
Tooling
Using the wrong cutter for an application
Entering the wrong size diameter and
programming with tool compensation.
Cutting too deep
No coolant
Can Contribute To:
Poor finish
Machine chatter
Excessive speeds and feeds can break cutting
tools or wear tools prematurely.
Poor finish
Parts incorrect size
Part dimensions incorrect
Driving and cutting forces cause deflections,
since no material is totally rigid
Machine chatter
Poor finish, decrease the life of the cutter

4.1.4.1 Spindle Speeds
Spindle speeds are influenced by a number of variables:
•
Material
•
Rigidity of the Machine Setup
•
Coolant
•
Cutter type, material and diameter
•
Cutting Depth
As a general rule:
•
Lower spindle speeds are used to machine hard or tough material or where heavy cuts
are taken.
•
Higher spindle speeds are used to machine softer materials in order to achieve better
surface finishes. Higher speeds also apply when using small diameter cutters for light
cuts on frail work pieces and delicate setups.
Note: Cutter diameter greatly affects spindle speeds. The larger the diameter, the lower the spindle speed.
4.1.4.2 Feedrates
Factors that affect feedrates:
•
Depth and width of cut
•
Design or type of cutter
•
Sharpness of the cutter
•
Workpiece material
•
Type of finish or accuracy required
•
Climb or conventional milling
If a fine finish is required, reduce the feed rather than increase the spindle speed. Cutters
are dulled by higher spindle speeds rather than high feedrates.
4.2 The Mechanical Drive Train (X, Y)
Indications:
• Troubleshooting instructions indicate that the drive train is potentially the problem and
other (more easily checked variables) have been exhausted.
•
Roughness, looseness, tightness or jamming movement in the table or saddle.
1. Check for machine considerations, especially gib locks and gib adjustments.
See Gib Adjustments section
2. Check the torque of the axis in three places (both ends and center of ball screw) along
the length of the ball screw. The torque should be within 2 or 3 in-lbs across the length
of the ball screw. If it is not, chances are the ball screw is misaligned. A misaligned ball
screw can lead to parts being out of round and servo problems at low feedrates. A bad
ball screw can also cause high torque, although this is highly unlikely. See Sections 4.2.1
and 4.2.2 for more information.

The following steps take you in logical sequence through the assemblies for the knee
mills. For drawings of these assemblies see Figures 31 and 32 in Section 5. These
instructions break the machine down from fully assembled and point out the areas to look
at specifically.
3. Check that the belt is properly tightened. A loose belt can lead to excessive backlash
compensation values on motor encoder only machines.
4. Check that the nut that tightens up against the ball screw pulley is tight. If this is
loose the pulley may not run true on the ball screw.
5. Check that the tapered sleeve that seats the pulley has not clamped to the ball screw
prematurely. It should be seated firmly against the pulley. Tightening the nut may
not have ensured this. Also make sure the pulley is keyed to the ball screw.
6. Ensure that the screws that hold the bearing housing in place to the bracket are not
loose.
7. Ensure that the Clamp Nut is secured. The following applies to the clamp nut:
•
When loosening, make sure to back out the 10-32 screw from the clamp nut.
•
When tightening, snug the 10-32 screw so the clamp goes onto the ball screw
thread with some drag. Thread it onto the ball screw and torque the clamp nut
to 50 ft/lbs and then tighten the screw down.
8. Take out the angular contact bearings and inspect them. They should roll smoothly
and be lightly greased. If not, replace them. When putting the bearings back into
the housing make sure to put them in correctly. Failure to do this will cause
problems. The thin race of each bearing should be facing inward toward the spacer
ring.
Note: the bearing housing and spacer ring are matched sets - keep them together.
9. Check the ball screw mounting to the yoke. Make sure the SHCS are tight.
10. Inspect the ball screw, ball nut and yoke for the potential problems shown in the
chart on the next page.
CAUTION!
Unlike a lead screw, do not unscrew the ball screw from its nut. This will destroy the ball screw!
Potential Problem:
Bad ball screw
Check By:
• Visually inspecting the ball nut - if the nylon seal is broken or deformed,
if contamination has visibly entered the ball nut or if balls are out of the
ball nut, replace the ball screw.
• Cranking the ball screw through a significant part of its travel. If it
jams, feels loose or has rough spots, replace the ball screw.
• Using the dial indicator on a vertical flat of the ball screw to check for
backlash between the ball screw and ball nut.

Potential Problem:
Ball nut not tightened to
the yoke
Yoke loose in the saddle
Oil lines sheared
Oil line blockage
Ball screws not aligned
properly
Check By:
• Inspection for space between the head of the bolt and the ball nut i.e.
the retaining bolt has bottomed out in its thread and is not securing the
ball nut to the yoke properly.
• Inspection for any motion of the yoke or looseness in the Yoke
mounting screws.
• Visual inspection.
• Pump the oil and ensure that it flows evenly to the ways and ball
screw.
• Measure from the ball screw to the back of the saddle on both sides of
the yoke (the table must be removed). The measurements must be
within ±.005” end to end. See above explanations.
Note: Ball screws are inspected throughout their entire travel for backlash and consistent torque. A
ball screw should be good for millions of inches of travel if installed properly. Do not be too quick to
replace a ball screw if there is insufficient indication that it is bad; this will just be a costly delay to
resolving the real problem.
4.2.1 Keys to Ball Screw Alignment
•
X-axis – there are 3 components that can cause misalignment: the yoke, the left side
bearing housing bracket, and the right side bearing housing.
•
Yoke – the yoke is aligned at the factory and pinned in place. It is aligned to within
+/-0.0005” with a precise alignment tool. The yoke most likely is not causing the
problem. If this were the problem you would need to remove the pins and align the X
ball screw with the back of the saddle. Drill new holes and pin the yoke in place. The Yaxis ball screw bore is machined perpendicular to the X bore. If the X-axis is aligned the
Y-axis will also be aligned.
•
Left side table bearing housing – this is most likely the cause of the misalignment.
To align the bracket and bearing housing, move them as close to the yoke as possible.
Loosen the bracket bolts and bearing housing bolts and then retighten. This should allow
the bearing housing to align itself up with the yoke.
•
Right side table bearing housing – once again move the bearing housing as close to
the yoke as possible. Loosen the bearing housing and retighten. This should allow the
bracket to align itself. If you do not move the table toward the yoke the ball screw will
tend to bend down slightly and cause misalignment.
•
Y-axis – the only component that can cause a misalignment problem is the motor
mounting bracket. To align this bracket, move the saddle as close to the front of the
machine as possible. Loosen the bracket and then retighten it. Once again moving the
saddle forward allows the yoke to be as close to the bearing housing as possible.
4.3 Computer/Pendant Diagnostics
The pendant consists of 2 separate modules: the computer module, and LCD
screen/enclosure.
In general, the pendant/computer module is best diagnosed by eliminating all other possible
alternatives. The following table lists some problems and what these problems can lead to.
61
Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
Possible problems
Poor cable connections
Pendant locks up
No voltage to RSG port
Low voltage to flash drive or slave board.
Flash disk failure
Floppy disk failure
LCD backlight burns out
Faulty E-stop switch
Overlay failure (keys on pendant)
Low voltage to pendant or current spikes
Can lead to
There are 4 cable connections (6 spindle control) to
the left side of the pendant. Make sure all cables are
properly fastened.
Press the E-stop button and see if lock up clears if not
then do the following:
Turn the pendant off, wait at least 30 seconds, and
turn it back on and check to see if the malfunction has
been reset.
RSG will not work – should be 5 DC volts present
Check with a voltmeter.
Can cause the system to lock up and the flash drive to
act abnormally. Check voltage to power cable at flash
drive module with voltmeter. It should be 4.8 DC
volts and above. Lower values than this can cause
problems.
If the flash disk fails, the system will not boot up or
operate. It will need to be replaced. All programs
and machine configurations will be lost. Make sure to
back up your flash disk from time to time.
Will not allow user to save or pull up programs from a
floppy disk. Can the floppy drive format a disk? See
Section 4.3.1.
Check all cable connections to LCD, distribution board
and computer module. Make sure the power is turned
off before doing so.
It can be stuck open or closed (pressed). If it is stuck
closed the pendant will need to be replaced because
the user will have no way to get rid of the message. If
it is open it will allow the machine to still operate but it
will be unsafe for the user. The pendant will still need
to be replaced.
Certain buttons on overlay do not work. Do code 81
to verify each key beeps.
1 amp fuse in pendant blows. Pendant will not turn
on.

4.4 Motor Diagnostics
The Motor subsystem is comprised of 3 parts: The Motor Encoder and the Motor and Servo Driver.
The motors are powered by 110 VAC voltage. The servo driver is also an integral part of servo
system, which is discussed in detail in the next section.
WARNING!
62
Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
Do not work with the motors unless the power is disconnected from the machine. The motors
are run by 110 VAC. There is possibility of death by electrocution!
Rarely do both the X and Y motor/servo systems fail at the same time and in the same way. So, if
your problem is occurring on both axes, its source is probably somewhere else.
4.4.1 Cable Connections
Check the motor cable connections on the cable breakout box. Verify there are no pushed in
pins on the connector.
4.4.2 To Check the Motor Encoders
If the motor encoder inside the motor has failed or is not reading the machine will fault out
on that axis. Do the following to verify this problem:
Motor encoder only machines – run Service Codes 100 or 131. This will display on the DRO if
the motor encoder is counting. If the axis does not count, the encoder is not counting. This
means either the encoder or the cable is the problem. Visually check the cable for any
problems. If the encoder has failed the motor must be replaced.
Motor encoder and secondary feedback machines – run Service Codes 100 or 131. Both the
motor encoder and sensor or glass scale encoder should count on the DRO screen. The
motor value should be displayed under the Z-axis and the sensor or glass scale under the X
or Y-axis depending on which axis you are doing.
4.4.3 Encoder Counts to Pendant
Before replacing the motor due to a bad motor encoder it is a good idea to check the cables
that take those signals back to the pendant. If these signals are not getting back to the
pendant then the axis will fault. Check the following cable connections.
•
•
•
Umbilical #1 and #2 at the cable breakout box
Umbilical #1 and #2 at the pendant
Umbilical #1 carries the X and Y-axis signals and Umbilical #2 carries the Z signals.
4.4.4 Moving Problem from One Axis to Another
Another way to troubleshoot a problem with a particular axis is to swap parts from 1 axis to
another to see if the problem moves. If the problem moves then that component is faulty.
See the example below.
Symptom – X Axis will not move and faults
This particular problem can happen because of any of following reasons: bad motor, servo
driver, or computer module. In some cases it is not obvious which component is causing the
problem. This example will help us pinpoint the problem through a trial and error process.
Let’s assume we have narrowed it down to the servo or electrical systems and the Y-axis has
no problems. Lets also assume it is not an obvious problem like a loose connection.
Swap these components
Physically switch the X and Y
motors
Results
Has problem moved to Y-axis? If yes, replace motor. If no,
the motor is not the problem.
4.5 Servo Driver
Note: the Servo Driver is located in the black box on the side of each motor.
63
Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
Indications:
• Problems moving just one axis, including hard turning in one or both directions.
Servo Types:
• X and Y servos are identical
Objective:
• Isolate the problem to the particular Servo Driver
Steps:
1. Turn off and unplug the system.
WARNING!
Do not work with the Servo Driver unless the power is disconnected from the machine. There is
possibility of death by electrocution!
2. Physically swap the servo module from the axis that is not working to one that is.
Note: To avoid pulling the wires out of the connector, use the loop to pull the connector from the Servo
Driver.
If the problem moves to the other axis and clears up from the original axis, replace the Servo
Driver.
4.6 Glass Scales
Glass scales are used on the X and Y-axis for secondary feedback. They are optional on the
TRAK Knee mill machines. The Z glass scale comes standard with the machine.
4.6.1 Alignment of scales
•
X Axis - The X-axis scale must be aligned within 0.005” in the up and down direction over
the length of the scale for proper operation. Misalignment can cause the scale to not
read in the certain areas of the scale that are not aligned with the reader head. If this
happens, the axis will mostly likely fault out in this area. Also make sure the mounting
hardware for the reader head is tight. Loose hardware can cause excess backlash when
reversing direction.
To align the scale, place a 0.001” indicator on the bed ways and on top of the scale
extrusion. Move the table along its full travel from one end to another to verify it is
aligned. If the scale is misaligned loosen the 2 screws at either end to shift the scale up
or down as needed. You will also need to loosen the center support bracket to allow the
scale to pivot.
•
Y Axis - The Y-axis must be aligned in the up and down direction and must be parallel to
the Y-axis way surface. Both surfaces must be aligned to within 0.005”. Failure to align
the scale properly could cause the same problems as mentioned above. Mount your
0.001” indicator on the saddle and move the Y-axis back and forth along its travel.
•
Z Axis – The Z scale must be aligned parallel with the quill. Make sure the gap on the
readerhead is consistent along the length of travel. Align the scale within 0.005” up and
down.
See Figure 28 in Section 5 for an illustration of the Z glass scales.
4.6.2 Measurements Do Not Repeat
1. Determine if the error in repeatability is random or accumulating:
•
Mount a dial indicator in the quill.
64
Southwestern Industries, Inc.

•
•
•
•
•
•
Touch off a fixed point on the table and set the DRO to 0.
Traverse away approximately 6 inches.
Return the touch off again.
Write down the reading on the DRO.
Do not Re-zero the DRO, traverse away and return several times.
Write down the DRO readings
Random error will be unpredictable and give scattered readings, adding and/or subtracting
the error after each traverse with no pattern. See Step 2.
Accumulating error will add roughly the same amount to the reading after each traverse.
See Step 3.
2. For random error, look for problems in the set-up of the glass scale that have resulted in
a loss of rigidity. Common sources of random error include:
•
•
•
•
Loose scale mounting hardware.
Loose reader head.
Very loose motion of the table or saddle.
Loose cable connection
3. Accumulating error is commonly the result of:
•
•
•
Scale out of parallel to the axis travel.
Dirt or chip on the glass scale.
Broken glass.
4.7 TRAK Sensors
TRAK Sensors are used on the X and Y-axis for secondary feedback. They are optional on
the TRAK SMX knee mill machines. The following section talks about some of the common
symptoms associated with a problem sensor and how to isolate or fix the problem.
Common symptoms
•
Faulting Axis
•
The DRO measurements do not repeat
•
The DRO measurements are not accurate
Objectives:
•
To determine if the TRAK Sensor is bad and needs to be replaced.
•
To determine if there is a problem with the sensor set-up
4.7.1 Faulting Axis
If a sensor has stop reading and you try to move an axis, the axis will run away and fault.
Our control uses the counts from the sensor and motor when reading position. If either one
of these signals is not working our system will fault.
1. The first thing that can be done to see if the sensor is at fault is to turn off the sensor on
the axis in question. This will allow the system to run only on the motor encoders. If the
fault continues then the sensor was not the problem. Turn the sensor back on. See the
service code section for a codes needed to turn the sensors on and off. Also, run code
100.
65
Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
2. The next thing to do is to visually inspect the sensor and base to determine if there has
been a crash. A damaged base will usually have crinkles in the small, spring plates on
the front and back.
3. Next make sure the sensor is preloaded correctly against the running surface. There is a
setscrew on the base that allows for adjustment.
4. If no outward signs of damage are present, remove the sensor from its base, and inspect
the wheel for damage and wear.
If the wheel is worn smooth in the center, replace the sensor.
Note: Sensors should not wear smooth for many years of normal operation.
5. If the sensor looks normal, it is probably OK and there is a mechanical obstruction
somewhere in the set-up. Look for the following possible problems:
•
Broken sensor base
•
Broken bracket
•
Sensor tilted too much (so that the wheel is not engaging the running surface)
•
Sensor chip scraper has doubled back and is pushing the wheel away from the
running surface
•
Sensor chip scraper is defective or has worn and is pushing the sensor unevenly
4.7.2 Measurements Do Not Repeat

•
very loose motion of the table or saddle
•
loose clamp screw

ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
3. Accumulating error is almost always the result of the wheel not traveling in a path
parallel to the motion of the axis. This causes the wheel to skip at certain regular points
in its travel.
•
•
Inspect the base to determine if it has been damaged. A damaged base will usually
have crinkles in the small, triangle-shaped plates on the front and back.
Use a bubble level or an indicator to adjust the puller screws so that the base is
parallel to the running surface.
•
Inspect that the sensor is not cocked so that the case contacts the running surface.
•
Inspect the wheel for chips that are adhered or for gouges.
4.8 Electrical
4.8.1 Checking A/C Voltage
This procedure tests for the 115V power for the control.
• Use a Voltmeter, reading A/C volts.
• Acceptable range is 100V to 130V.
Note: systems running consistently close to the low values may have problems when normal voltage
fluctuations push the voltage out of the acceptable range.
Test the following in the order presented:
Problems Here:
1. The wall outlet.
•
•
2. The control power cord from the wall.
Check the end that goes to the electrics
box.
3. Check the top fuse on the electrical cabinet.
It should be an 8-amp fuse.
3. Check the 110-power cord to the pendant.
4.8.2
•
•
•
May Indicate:
Fuse blown in the shop electrical panel.
Incoming service from local utility is bad.
Call the electric company.
Power cord defective.
If this is blown then power will not reach
the 4 outlets on the electrical box.
Power cord defective
Checking Fuses
CAUTION!
Turn off power before removing and replacing
There are 4 fuses to check in the system. There are 2 in the pendant and 2 in the electrical
cabinet, and one on the breakout box. The top fuse in the electrical cabinet is 8 amps and
fuses power to the pendant. The bottom fuse is 5 amps and fuses power to the auxiliary 1,
auxiliary 2 and lube pump outlets. The 2 fuses in the pendant are 1 amp and 12 amps. The
12-amp fuses the cable breakout box, and the 1 amp the pendant.
If you have the auxiliary function option then there is 1 more fuse to check on the cable
breakout box for the coolant or mister option.
To check fuses:
1. Use a Volt/Ohmmeter; select “OHM”.
2. Remove the fuse completely from the pendant, electrics box or cable breakout box.
3. Place a lead of the meter on each end of the fuse.

•
A good fuse reads 0 (zero) or close to it.
A bad fuse reads Open or Infinity.
4.8.3
Cable Breakout Box Connections
This module is located on the back side of the machine. It consists of 3 motor connections, 3 limit
switch connections, 3 encoder connections and an E-stop connection.
Machines with an auxiliary function option have 2 more outlets. A 110 V outlet for a coolant
pump or air solenoid and an indexer outlet.
The coolant pump signal and indexer signal comes down from umbilical #2.
4.8.4
Cable Connections
The TRAK knee mill machines use 10+ cables to communicate between systems. It is often
the case that what appears to be the failure of an electrical component is actually attributable
to a poor connection.
Indications:
•
•
•
Control problems, chronic or intermittent.
Motor problems
Measurement problems.
Explanation:
1. Turn off and unplug the system from the wall.
CAUTION!
Do not plug and unplug connectors with the system power on. This may cause damage to the
connector board and harm to the technician.
2. Visually inspect the connections for excessive debris, moisture, or obvious damage.
3. Carefully clean any chips away from the connectors.
4. One-by-one, take out each connector and then plug them back in. Do the same at the
computer/display.
5. Make sure to tighten up the screws on each of the connectors.

Spindle Control Electrical Box
The spindle control electrical box is made up of the following main components:
1. AC drive – used to control the spindle motor.
2. 4 output 110 volt outlets – 1 outlet is used to power the pendant, 1 is used to power the
lube pump and is turned on based on the spindle being on, 2 additional outlets.
69
Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
3. 2 braking resistors – used to brake the spindle motor. The mechanical brake should not
be used to brake the spindle. To verify the resistors are good, measure the resistance
across B1 and B2 of the AC drive. For 3 HP machines it should read 60 ohms and for 5
HP machines it should read 32 ohms. Values lower or higher than this could be one or
both resistors are bad.
4. Relay – used to turn on and off the lube pump and spindle motor fan.
5. Spindle control PCB board - controls the auxiliary signals from the pendant to the AC
drive and electrical outlets. The following explains the LED lights on the spindle control
board. There are (2) 10 LED segments on the board. Not all of the LEDs are used. See
figure 21 for an illustration.
1st 10 LED Segment
4. LED labeled Gear 1 – this light should be on whenever the machine is in low gear. LEDs
labeled Gear 2 thru Gear 4 are not used.
5. LED labeled SPD-FAULT – this light will be on whenever the AC drive is in a fault
condition, which includes an E-stop message from the pendant.
6. LED labeled SPD-RUN – this light should be on whenever the spindle is on.
7. LED labeled SPD-ENABLE – this light should be on whenever you are in DRO, tool setup
and RUN mode.
2nd 10 LED Segment
1. LED labeled E-STOP OUT – this light should be on whenever the E-stop is in the out

2. LED labeled LATCH RELAY – this light should be on when the spindle is running or if the
spindle is not running and the fwd/rev switch is in the off position when in DRO, tool
setup or RUN mode. Note – if spindle won’t turn on and the spindle is enabled and the
e-stop is out, then either the fwd/rev switch is bad or the spindle control board is bad.
3. LED labeled TAP MODE – light should be on whenever you are not tapping. Light will be
off when in the tap event. Not applicable to 2-axis knee mills or retrofits.
4. LED labeled TAP REVERSE – this light will be on when the spindle changes direction at
the bottom of a tap event and back off after the spindle changes direction once outside
of the tap event. Not applicable to 2-axis knee mills or retrofits.
5. LED labeled REV-RELAY – when fwd/rev switch is in reverse this light will be on. Note –
this does not mean necessarily that the spindle will be running this direction.
6. LED labeled FWD-RELAY – when fwd/rev switch is in forward this light will be on. Note –
this does not mean necessarily that the spindle will be running this direction.
7. LED labeled Z-LIMIT PLUS – this light will be on only when the Z-axis plus limit switch is
triggered. This only applies to a 3rd axis product.
8. LED labeled Z-LIMIT MINUS – this light will be on only when the Z-axis minus limit switch
is triggered. This only applies to a 3rd axis product.

Machine Set-up Codes
The following codes are used primarily when setting up a new machine. To get to any of
these codes go to Service Codes, press “B” and press the code you wish to view.
4.9.2.1 CODE 11: Hysteresis
Note: This code is use only for systems with Sensors or Glass Scales on the table and saddle.
The Code 11 service routine checks the readings of the motor encoder against the sensor
encoder. It is a measurement of how much motor motion is necessary to create table or
saddle motion. This test helps us to look at two things:
•
Play: How much backlash must be taken up when motion is reversed.
•
Friction: How much the mechanical components must be "torqued up" in order to break
the friction and create motion.
The Code 11 procedure is very useful and will help in diagnosing all types of motion and
performance problems.
1. Position the table and saddle in the center of travel. Note: You will lose your DRO position
reference.
2. Go into the Service Codes and input Code 11.
3. The system will run the checking routine automatically and then display the values in the
position readout.

Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
As an overall measure of the system hysteresis, we are looking for the X and Y values to be
less than .004". A value greater than this indicates a problem with either excessive friction or
play that may affect the finish or accuracy of machined parts.
4.9.2.2
CODE 12: Feed Forw ard Constant
The Code 12 procedure helps the control “learn” the friction characteristics of the machine by
sending a graduated series of motor signals and observing the results. The process takes
less than 30 seconds to run. It is both a diagnostic routine that displays values, and a
routine that sets the parameters of the control for the particular machine.
The Code 12 is used for diagnosing and resolving:
•
Problems with machine motion.
•
Machined parts come out bad – especially poor finish.
Note: Code 12 routine will set the parameters for the particular machine and its particular situation.
If the machine changes its friction characteristic, the Feed Forward Constant should change too, or
the system will not servo properly. Whenever gibs are adjusted or a heavy workpiece has been added
to the table, you should run a Code 12. When the heavy workpiece is removed, Code 12 should be run
again.
1. Position the table and addle in the center of travel. Note: You will lose your DRO position
reference.
2. Go into the Service Codes and input the Code 12.
3. Press Auto
4. The system will run the routine automatically and then display values on the position
readout.
Explanation
Typical values should be between 4.04 and 11.11 are considered normal for each axis. Higher
values indicate excessive friction in the system. Lower values indicate a loose system and
may mean a gib adjustment is necessary. Value 4.04 means the friction is a factor of 4 in
one direction, and 4 in the other direction. The values should be within 3 or 4 of each other
in both directions. A value of 6.08 would still be considered normal.
On S products, do not equate Code 12 values to torque on ballscrew. Measure friction in
system with an in-lb torque wrench.
The feed forward gain can be adjusted manually by pressing the manual button. Choose the
axis you would like to change and then enter values in the positive and negative direction to
adjust. Adjusting the gain can help solve circularity problems. Default values can be set by
pressing the Reset button. The manual feature should only be used in extreme cases where
the AUTO routine did not solve the problem. Manual adjusts above 12 may lead to servo
related problems.
4.9.2.3
CODE 100: Ax is Open Loop Test
Code 100 procedure is used to diagnose problems with the configuration of the system, the
encoders and incoming A/C voltage.
CAUTION!
During this procedure, the designated axis will be given a command to move at maximum speed for 1
second in the direction you choose. Avoid crashes by making sure the quill is out of the way and by
starting with the table and saddle centered. MAKE SURE THAT NO ONE IS STANDING IN THE WAY
OF THE TABLE OR SADDLE!
Note: You will lose the DRO reference position.
This procedure is to be run for each axis that is servo-driven, and for both the plus and minus
direction for each axis.

If the motor encoder and sensor or glass scale reading is not within this value, then the
one that is out of specification may be the problem. If one of the encoders is not reading
then it will need to be replaced.
•
The feedrate should be a minimum of 120 ipm.

This code is used to check if the keyboard is functioning correctly. It allows you to test each
key on the pendant individually. When you press the keys, the corresponding box for that
key will highlight on the screen. The pendant will also beep, indicating that the key is
working correctly. If one of the keys does not work the pendant assembly may need to be
replaced. If none of the keys are working chances are that the computer module will need to
be replaced.
4.9.3.3
Code 131: M anual DR O
A manual diagnostic routine to check the motor encoder and table encoders. Turn the X
hand wheel to display the encoder readings. This code will display the actual DRO counts
and the raw encoder counts.
4.9.3.4
Code 132: Electronic Hand W heel Test
4.9.3.5
Code 314: Toggle test lights ‘on’ in status line
Turn the X, Y, or Z-axis electronic hand wheel. The display should show movement as the
hand wheel is being turned. There should be no skipping and it should count smoothly while
the hand wheel is being turned. One revolution of hand wheel should read 0.2000” when in
fine mode and 0.800” in course mode
This code toggles on and off 2 test lights that appear in status line. The top light signifies if
the master software is working. If functioning it should flash a green light. The bottom light
signifies if the slave firmware is functioning. It will appear orange in run mode when it is
processing information. Pressing the mode key will change this orange box to black. The
orange box will also change to black when the program you are running reaches the 3rd event
from the end of the program. If the firmware is locked up no keys will work. This code is
useful for diagnosing intermittent problems with the control locking up.
4.9.3.6 Code 319: Error Log
This code when turned on captures the commands that were sent to the servo system. It
includes items such as positioning commands, errors, stop and go commands, etc. It may be
helpful for identifying problems between programmed commands and executed commands.
To turn on the error log press the F6 softkey. The page forward and backward keys allow
you to scroll through the file one page at a time. The data forward and data backward keys
allow you to scroll through the file one line at a time. The data bottom key takes you to the
bottom of the file and then changes to data top which will take you back to the top. The file
will capture data until the file reaches a size of approximately 600 Kb. At this time the file is
saved to a backup file and the original file is cleared and data is once again captured. Once
again as the file reaches a size of 600 Kb it copies over the previous backup file. From here
the user can save the file to the floppy drive or an external drive by following the instructions
on the screen. Once this in done it prompts you for which file you want to save to disk. The
F1 key saves the current file to disk and the F2 key saves the backup file to disk. To clear
the files press the F7 softkey.
4.9.3.7
Code 324: Toggle Sim ulation M ode
Simulation Mode allows the control to run a program without actually moving the table. It is
helpful in diagnosing Computer/display problems.

This turns off the beeper to the control keys.
4.9.4.5
Code 129: Arc Accuracy
When the SMX control operates at high feedrates it may create small part machining errors
as it goes around sharp corners. This exists on all CNC’s and is commonly called a “following
error.” The control is factory preset to allow a maximum following error of 0.001 inch. The
feedrate will automatically be adjusted around sharp corners so as to not violate this limit.
This code only applies to arcs that are programmed and ones that are created in the tool
path to generate the shape you want. This code will not make a difference on mill moves.
You may adjust the maximum following error to a value as small as .0001 inch. However, the
smaller the value, the slower the feedrate around corners.
To input a new Following Error use the following procedure:
Follow the instructions on the screen and input the Following Error value (from .0001 to
.0100) and press INC SET.

R eplacing the M 5 Base
Whenever you replace a cable or reroute a cable it is very important to keep the power cables
and logic cables separated from each other. The power cables consist of the (3) 110-volt motor
cables and (2) 110-volt power cables for the pendant, and a coolant pump or solenoid power
cable. The logic cables are used to carry encoder signals between the cable breakout box and
computer module. Mixing of the power and logic cables may cause noise from the power cables
to interrupt the signals in the logic cables. This can lead to intermittent axis faults or
repeatability problems. See Figure 15 and 16 for a layout of the cable connections.
See Figures 25 and 26.
1. Remove the sensor by removing the clamp screw and then backing the load screw out a few
turns. The sensor should lift off the base easily.
2. Remove the old M5 Base by removing the two 1/4-20 hex head screws that are threaded
into the base.
3. Assemble the new base as per Figure 25.
4. Use a bubble level to align the raised bumps on the base with the table for X axis or saddle
ways for Y-axis.
5. A dial indicator may be used to align the bumps on the base instead of a bubble level.

5.1.7.1
R em ove the X, Y or Z Glass Scale
1. Unplug the glass scale connector from the cable breakout box.
2. Unbolt the reader head of the glass scale from its mounting surface.
3. Unbolt the glass scale enclosure from the table on X or the mounting spar on Y.
4. Install the head alignment bracket that came with the replacement scale to this scale to
secure it for shipping back to SWI. Failure to do this may cause the glass scale to get
damaged during shipment. The head alignment bracket secures the reader head so it
cannot move and damage the glass in the scale.
Note: 1st align the reader head on the new scale before removing it to fasten the old scale.
CAUTION!
Once the head alignment bracket is installed, do not traverse the axis or the
reader head will break.
5.1.7.2
Install the X or Y Replacem ent Scale
CAUTION!
If the scale is not long enough for the table, it will break when the machine is
traversed past the scale travel.
1. Mount the scale to the back of the table or Y-axis mounting spar.
2. Align the sale so that it is within +/- 0.005" end to end.
Notes: For the Y-axis, the mounting spar should already be aligned. It must be parallel to the Y-axis
travel within +/-.005" end to end both horizontally and vertically. The mounting spar can be aligned
in and out by the use of the adjustment screw.
3. Line the reader head up with the mounting holes on the back of the saddle for the Xaxis or the bracket on the Y-axis.
4. Install the reader head bolts but leave them loose.

5. Use the jackscrews on the reader head to compensate for some gap between the reader head
and the reader head mounting bracket. Leave the alignment brackets attached to the reader
head. This bracket assures the reader head is aligned to the glass scale.
6. Tighten each jackscrew until it touches the bracket and then back it off 0.001” or
0.002”. Use a feeler gage to set the gap.
7. Tightening the reader head mounting screws. This ensures the reader head is aligned
within a few thousandths.
8. Remove the shipping bracket that fixes the reader head to the scale for shipping.
CAUTION!
After the reader head is attached to the reader head-mounting bracket, do not move
the machine axis until the shipping bracket is removed. This will break the reader
head. This is not covered under warranty.
See Figure 29 for an illustration of how to align glass scales.
5.1.7.3
Install the Z-Ax is Glass Scale
See Figure 28.
1. Check the tram of the head in the X direction. If it is within a few thousands then
continue on. If not tram.
2. Assemble Z-axis glass scale mounting bracket and mount to head. Items 1, 2, 3 and 4.
Tap items 3 and 4 together and tap item 3 into the quill stop knob. Leave the bolt loose.
Use 2 screws (item 6) and mount item 4 to the side of item 2 using a spacer between
both items to provide a gap of approximately 0.040” between Items 2 and 4. This is to
make sure item 2 does not rub against item 4.
3. Align the glass scale bracket (Item 2) with an indicator and tighten the mounting screws.
Leave the quill stop knob screws loose. Remove the spacer and bolts from Item 4.
4. Unscrew the shipping protection screw from the scale.
5. Mount the glass scale to the mounting bracket and align it with an indicator. It needs to
be aligned within 0.008" with respect to the quill. Tighten the screws down.
6. Fasten the readerhead to the readerhead bracket.
7. Move the readerhead up and down the glass scale and make sure the gap is consistent
between the readerhead and the glass scale. Tighten the screw to the quill stop knob.
8. Remove the red head securing plate.
9. If the gap is not consistent between the readerhead and the glass scale when moving
the quill up and down then adjust the angle of the scale to make the gap consistent.
CAUTION!
The gap must be no larger than 0.060” between the readerhead and glass scale.

5.1.8 Power Drawbar
A power drawbar is an optional item on a TRAK Knee mill machine. It is bolted to the top of
the head by the use of 3 SHCS. Some machines may require a washer to space the unit up
to the proper height to allow the drawbar to engage properly.
Air Regulator and Oiler - This unit requires between 80 and 100 psi to operate properly.
Some units work fine at 80 psi while others may need 90 or 100 psi. It is also important to
make sure the oiler for this unit is kept filled with oil. Fill the reservoir about 2/3 full using
AIR TOOL OIL ONLY. Failure to do this will not allow oil to lubricate the internal
components of the unit and it may wear out prematurely. It is also important to make sure
the oiler is set properly. To set the oiler, first close the adjustment screw (CW) on top of
the oiler completely making sure to not over tighten. Then open the screw (CCW) between
½ to ¾ of a turn. Any more than this will cause too much oil to get into the unit and oil
may come out of the exhaust port of the unit.
Tool Alignment Device - This unit also comes with a tool alignment device, which
attaches to the bottom of the spindle. This device allows the tool to easily be aligned with
the dogs when loading a tool.
Note: Only used on K4 machines
CAUTION!
Some tools may not work with this device and the original spindle dogs will need to be used.
The original spindle dogs are shipped with each machine in the toolbox. Some boring bar
holders may not work with this device.

3. Remove the left side table tray by pulling it up, and remove the X motor (If machine has tray).
4. Remove the motor mounting bracket and bearing housing.
5. Remove the right side bearing housing.
6. Loosen the table gibs. Slide the table to the right and on to a lift that will support the table's
weight. Slide the table until the yoke is exposed.
CAUTION!
The weight of the table must be supported by the lift to prevent damage or
breakage to the dovetails.
7. Remove the 5/16 x 1" screws holding the ball nut to the yoke and loosen the 4 screws
that mount the yoke to the saddle. Remove the oil line.
8. Tilt the yoke (it is pinned) to remove the ball screw.
9. Remove the elbow and setscrew from the old ball screw flange and fit them similarly in
the new ball screw.
10. Pump oil to be certain it flows through the oil line and then attach the oil line to the elbow.
11. Reassemble all assemblies.
Important: The clamp nut must be reassembled as follows:
•
Install rear bearing and seal into bearing housing and slide housing onto the ball
screw. (Note: Letters on bearings must face each other in the housing.).
•
Thread the split nut onto the ball screw and tighten the #10-32 clamp screw until
you feel the split nut contact the ball screw threads. It should drag as you tighten
the clamp nut.
•
Torque the split nut to 50 ft. lb.
•
Firmly tighten the #10-32 clamp screw to lock the clamp nut in place.
See the diagnostics section under Mechanical Drive Train for an explanation of how to align

5.2 Maintenance
5.2.1 Gib Adjustments
The objective of adjusting the gibs is to eliminate as much play in the table, saddle and ram
sliding surfaces as possible without having the tightness of the gib interfere with their free
movement and cause a decrease in the accuracy and/or performance of the machine due to
excessive friction.
5.2.1.1
Table Gib Adjustm ent, X-Axis
See Figure 39.
1. Clean all chips, dirt and excess oil from the table and saddle.
2. Center the saddle on the bed ways.
3. Move the table fully to the left side of the saddle.
Note: For machines that have excessive wear in the center of the table way, it will be
necessary to center the table on the saddle. The resulting adjustment of the gib will be
compromised to account for the varying clearance from the center to the ends of the table.
4. Attach a .0001 dial indicator with a magnetic base to the left front of the saddle.
Place the indicator stylus on the front surface of the table as close to the indicator
base as possible.
Figure 39
Table Gib Adjustment
107
Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
5. Move the left end of the table back and forth and note the amount of movement on
the dial indicator. Adjust the X-axis gib until the registered movement is .0010-.0015.
•
To adjust the gib for excessive clearance: Loosen the gib lock screw on the right
end of the saddle. Estimate the amount of gib lock screw adjustment required,
and tighten the gib lock screw on the left end of the saddle. Tighten the gib lock
screw on the right end of the saddle to lock the give in place, and recheck.
Repeat as necessary.
•
To adjust the gib for too small of a clearance: Loosen the gib lock screw on the
left end of the saddle. Estimate the amount of gib lock screw adjustment
required, and tighten the gib lock screw on the right end of the saddle. Tighten
the gib lock screw on the left end of the saddle to lock the gib in place, and
recheck. Repeat as necessary.

5.2.2 Calibration & Backlash Constants
Calibration and backlash constants were set as part of the installation and set-up of your
system. They should be re-set when indicated in the Troubleshooting section or after the
replacement of the Computer module, or any parts of the drive train.
5.2.2.1
X, Y, Z and Quill Calibration
Calibration is used teach the machine a known distance. We typically calibrate our
machines over a 150 mm distance. There is no limit to how far you can calibrate the
machine.
1. If you have installed TRAK Sensors, move each axis through its travel 4-6 times in order
to allow the gage wheel to establish its track.
2. Set-up a gauge block or standard and indicate it parallel to the axis you are calibrating.
Note: Put the display in Inch or mm to match your gage block. Recommended gage blocks are:
•
X and Y -- 150mm or 6”
•
Z -- 75 mm or 3”
3. Set a 0.0001” indicator in the spindle and move it up to one side of the gage block or
standard.
4. Go to setup mode, go to section “B” and press CODE 123.
5. Select the axis you want to calibrate X, Y or Z. For the quill press the F1 key labeled
QUILL. The Z key is used to calibrate 3 axis machines only.
6. Follow the instructions on the screen to complete calibration.

Backlash Com pensation
Code 11: Set X or Y backlash constant
Note: this procedure is on systems with TRAK Sensors or Glass Scales only.
Go to setup mode, go to section “B” and press CODE 11. Refer to service code section for
further explanation.
Code 127: Set X or Y Backlash Constant
Note: this procedure is only for systems without TRAK Sensors or Glass Scales.
Every mechanical system has at least a little backlash or lost motion. It is produced by the
small amount of play between the gibs and ways, and mostly by the accumulative bending
or elasticity of all the parts of the drive train under load. The backlash constant is factory
set, but may need to be adjusted periodically.

3. The X backlash identified and stored in Step 2 should be less than 0.003” on a new
machine. If it is appreciably larger, inspect the drive train for loose bolts, brackets,
bearings, etc.
The backlash can also be found manually with a 0.0001” indicator with the following
method.
•
Load the indicator to zero from one direction and zero out the DRO.
•
Move the indicator to 0.002” and then back to zero. Do not over shoot 0,
otherwise start over.

Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
•
Whatever number appears on the screen is the backlash value.
•
Enter this value into service code 128.
•
After entering this number redo the process. The DRO and indicator should
now both read 0.
CODE 128: Input Backlash Constant
Code 128 allows you to enter the backlash values for each axis. It displays the value after it
enters. This code is only used on machines with single feedback.
5.2.3 Head Rotational and Tramming
The TRAK knee head is free to rotate up to 90 degrees to the right or left. The K2 and K3
can also rotate 45° front to back. The K4 machine cannot rotate front to back.
5.2.3.1
To R otate the Head Side to Side:
1. Loosen the four locknuts.
2. Rotate the head with the adjusting worm shaft. When rotating to greater than a
45o angle, support head by hand.
3. Tighten the locknuts. Snug each locknut, then lightly tighten each locknut, then fully
tighten each locknut in a crisscross pattern.
4. Use the method shown in the figure below and a parallel bar to square the head to the
table.
5.2.3.2
Tram m ing the Head
The purpose of tramming the head is make sure the head is perpendicular to the top of the
table from both side to side and back to front.
Side to side tolerance – 0.001”
Side-to-Side Alignm ent
1. Make sure the machine is level.
2. Make sure the table has been clean and the Z gibs are adjusted properly.
Mount a dial indicator in a tool holder and mount in the quill.
3. Adjust the Y-axis so that the spindle is in the center of the table.
4. Adjust the Knee so that the dial indicator will reach the table.
5. Move the dial indicator to 6 o’clock position and adjust the face so the needle is zero.
6. Do a series of sweeps from 9 o’clock to 3 o’clock and check for the repeatability of the
setup. The head should be trammed within ± 0.002”
7. If the head is out of tram from side to side then loosen the 4 head bolts and rotate the
head with the worm shaft.
8. Once the head has been trammed, tighten the 4 heads bolts. Be careful not to move
the head while tightening. Tighten the bolts in a criss-cross pattern. Torque = 30-35
lb.ft.

Note: The head of the K4 milling machine is adjusted at the factory.
With the dial indicator sweep the table from 6 o’clock to 12 o’clock. The head should be
trammed within ± 0.0006” over 9 or 10” tram diameter. 9 or 10” is based on the table
width.
5.2.3.3 Back to Front Adjustment – K2/K3 only
1. Make sure the table has been clean and the gibs are adjusted properly.
2. Mount a dial indicator in a tool holder and mount in the quill.
3. Adjust the Y-axis so that the spindle is in the center of the table.
4. Adjust the knee so that the dial indicator will reach the table and lock the 2 clamps on
the knee.
5. Move the dial indicator to 6 o’clock position and adjust the face so the needle is zero.
6. Do a series of sweeps from 6 o’clock to 12 o’clock and check for the repeatability of the
setup. The head should be trammed as close as possibility to ± 0.0005”
7. Loosen the three bolts and adjust the tram with the bolt mounted on the top of the
ram.

Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
Once the head has been trammed tighten the three bolts. Be careful not to move the head
while tightening. Tighten the bolts a little at a time. (Note: the head must droop down
rather than up because tool pressure will take care of the extra 0.0005”.)
5.2.4 Limit Switch Option
See figures 64 and 65 in section 7.
The limit switch option design was changed from when we first released the SX control.
Early limit switch kits came with a single input limit switch as shown in the figure.

Description
Limit Switch Assembly with cable
The latest design consists of a limit switch with 2 inputs as shown in the figure. This means
1 input for each direction. On machines with electronic handwheels, when you hit a limit
the EHW will only allow you to move the machine in the direction away from the limit
switch. This will prevent the user from damaging the machine by hitting a hard stop.

X-Ax is Lim it Sw itch-Stop Installation and Adjustm ent
The limit switch-stops/cams for the X-axis are mounted to the front side of the table and
can be adjusted along the length of the T slot. Each limit switch-stop must be set to a
specific distance from the end of the table in order to maximize travel and simultaneously
prevent serious damage to the machine in the event of a crash. All limit switches are set at
the factory for maximum travel.
Procedure for Setting X Lim it Sw itch
1. Loosen the stops or cams on each side of the table.
2. Slide each stop or cam within the T-slot to the end of the table.
3. Slowly move the table to one side by hand until the end of the travel is reached.
4. In DRO mode set X = 0 ABS.
CAUTION!
The limit switch must be triggered a minimum of ½” before the machine reaches its travel
limits in both directions. This allows sufficient room for the servomotors to stop when the
limit switch is hit at 150 ipm.
5. Using the DRO display, back the table off 1/2".
6. Lock the limit switch bracket in place.
7. Jog the table at 100ipm to each side and verify that the limit switch is working properly.
Also, make sure that the table does not exceed its travel and crash.
5.2.4.2
Y Ax is Lim it Sw itch-Stops
The limit switch-stops for the Y-axis are mounted on the side of the knee. The limit switch is
triggered by hitting the cam stop on the saddle. The cam is placed to ensure maximum
travel. The 2 input limit switch design allows for slight adjustment of each cam.

ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
6. Remove the yoke from the saddle. Disconnect the oil lines from the yoke. If the yoke is
to be re-used, it will be necessary to remove the brass nut key and pins. If the kit came with
a yoke, the original yoke may be discarded.
7. Clean the X and Y-axis gibs, oil grooves and slideways thoroughly. Also remove the
sliding covers and clean them. Inspect the operation of the oiling system.
Note: Step 7 is worth extra care, especially with machines that have some wear, or new machines that
may have some protective covering on the ways. System performance depends on smooth motion.
7.1.2 X-Axis Ball Screw Installation - Part 1
The ball screws are to be installed in the following order:
• First - part of the X-axis ball screw assembly.
• Second - the entire Y-axis ball screw assembly.

9. In the ballnut flange there are two tapped 10-32 holes. One for the provided elbow oil
fitting, and one for a 10-32 setscrew. For the X ball screw put the elbow oil fitting in the
hole on the radius of the flange, and the setscrew in the hole on the flat. The function of
the setscrew is only to prevent oil from flowing out of the ballnut. Screw it as far as
possible being careful not to contact and deform the nylon wiper.
10. Attach the provided plastic oil line to the elbow oil fitting.
11. Slide the ball screw into the yoke with the flange of the ballnut to the left. Do not install
the 5/16-18 x 1 3/4” screw yet.
12. Secure the yoke to the saddle with the 4 screws, make it snug but not tight. You will
need to move the yoke a little to align the ball screw.
13. Secure the ballnut to the yoke with 5/16-18 x 1 3/4” screws.
14. (Optional) If the yoke was pinned previously, replace the pins and then tighten the yoke
to the saddle.
15. If the yoke was not pinned, it will be necessary to align the ball screw:
122
Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
Take measurement “A” on the left and right
sides of the saddle casting. So that the
measurements are comparable, measure from
the OD of the thread of the ballscrew on both
sides.
Note: If the back of the saddle casting is not a
suitable reference, it may be necessary to position
a piece of round stock inside the back dovetail to
be used as a reference point.
Adjust the position of the yoke until the two measurements are within 0.005” end to end
(maximum).
CAUTION!
The alignment of the ballscrew is crucial.
Misalignment can cause damage to the ballscrews and drive assemblies
as well as poor system performance.
16. Tighten the yoke to the saddle casting. Check the alignment again to be sure
the yoke did not move as it was tightened. Pin the yoke in position using the
provided roll pin.
7.1.3
Y-Axis Ball Screw Installation
Parts required
• Yoke kit (already opened)
• Y-Axis drive assembly 23083-xx
• Y-Axis ball screw
Figure 51
CAUTION!
Unlike a leadscrew never unscrew a ball screw from its nut.
This will destroy the ball screw.
17. In the Y-axis ball screw, put the 10-32 set screw in the hole on flat part of the
ballnut flange and the elbow oil fitting in the hole on the radius.
18. Attach the provided plastic oil line to the elbow oil fitting.
19. Pull the saddle all the way forward and install the ball screw into the yoke with 5/1618 x 1 3/4” screws. The flat of the
ballnut flange should match up with the flat on
123
Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
the yoke. These flats are there so that the yoke and ballnut will clear the bevel gear.
Check that these clear now by pushing the saddle back.
If the yoke provided in the kit does not clear the bevel gear, it will be necessary to
remove enough material from it so that it will clear.
Also check that the elbow fitting will clear the casting at the top front of the knee. If
it interferes, it will be necessary to screw it down more, or grind away the casting to
clear.
20. Route the oil line up through the hole in the saddle to the right rear of the yoke, trim it
appropriately and attach it to one of the oil lines of the machine.
(Kit Variation: some machines do not have separate oil lines running to each leadscrew. Use the
supplied T fitting to route oil to each ball screw.)
CAUTION!
Make sure that the oil line will not be sheared by the sliding
covers when the saddle moves.
(Kit Variation: on machines with oil restrictors on the yoke, use the supplied brass fitting and the
original restrictor.)

Figure 53
Bearing Housing
22. With the saddle all the way forward, install the assembly from the previous step
on the ball screw with the bearing seal towards the machine.
(Kit Variation: the Y-Axis bearing housing is designed to float to find its own center. For some
machines, the hole in the knee is too large for the flange of the bearing housing to contact. Use the
supplied backing plate shown below.)
Figure 54
Backing Plate
23. Install the bearing housing A on the ballscrews as shown in Figure 53. The angular
contact bearing should have the inner race, thin side in.
24. Install the clamp nut and torque to 50 ft/lb. Tighten the 10-32 x 3/4” screw on the
clamp nut.
Note: To keep the clamp nut from expanding while using the torque wrench, put in and snug the 10-32
x 3/4 setscrew. Tighten the cap screw after proper torque is obtained.
25. Turn the clamp nut until the flange of the bearing housing contacts the knee (or
backing plate, if one is used) and the saddle begins to move forward.
26. Install the Y motor mounting bracket. This bracket can vary from machine to
machine.
27. Install the remaining items on Figure 52.

Parts required: M250C sensor and included hardware
a) Put in pusher screws. These are the screws with the rounded ends.
b) Position base and install puller screws and spherical washer sets. Use the pusher
screws to square the M5 base to the running surface.
c) Adjust the puller screws so that the raised bumps on the front of the base are
parallel to the table.
Note: The drawing shows a bubble level used for this adjustment. Alternatively, you may use a
dial indicator set-up on the table.
2. Install the sensor on the M5 Base using the clamp screw. See Section 5.1.6.2,
Figure 26.
3. Load the sensor against the running surface (table or run bar) using the load screw.
The white lines on the side of the M5 base tell you when it is loaded correctly.
Note: You want to load the gage wheel against the running surface using the flexure of the M5
Base. Do not tighten the clamp screw fully until after loading the sensor.
7.7 X and Y Glass Scale Installation - Optional
The Acu-Rite Glass Scales are shipped with complete installation instructions including
illustrations. This section gives summary instructions for the installation of the glass scales
on knee mills. If more instructions are needed, please see the booklet provided with the
scales.
See Figure 29 in Section 5.
7.7.1 X Axis Scale Installation
Note: New Bridgeport machines have Acu-Rite scale mounting holes pre-drilled.
Caution!
If the scale is not long enough for the table, it will break when the machine is
traversed past the scale travel.
1. With the table centered, position the scale and readerhead to make sure that the scale is the
correct length. The readerhead mounting bracket is attached to the saddle and the scale is
attached to the table.
2. Mount the readerhead mounting bracket to the saddle. Snug the screws, but do not tighten
at this time, you will be making fine adjustments to the bracket’s position after the scale is
installed.
141
Southwestern Industries, Inc.
ProtoTRAK SMX K2, K3, K4 & Retrofit Safety, Installation, Maintenance, Service & Parts List Manual
3. Mount the scale to the table:
•
•
•
•
Transfer the center hole first to use as a pivot point.
Align the scale so that it is within 0.005” end to end.
Transfer the holes on the ends and install the screws.
Re-check the alignment.
4. From the readerhead on the scale, remove the nameplate, shield and wires so that the
mounting holes are accessible.
5. Attach the readerhead to the readerhead mounting bracket:
•
•
There are jackscrews on the readerhead to compensate for some gap between the
readerhead and the readerhead mounting bracket.
Before tightening the readerhead to the bracket, there must be a .002 - .003” gap
between the readerhead mounting bracket and the jackscrews. Tightening the mounting
screws will eliminate this gap.
6. Replace the wires, shield and nameplate.
Caution!
Do not pinch the wires.
7. Remove the shipping brackets that fix the readerhead to the scale for shipping.
Caution!
After the readerhead is attached to the readerhead mounting bracket, do not move the
machine axis until the shipping brackets are removed. This will break the readerhead.
7.7.2
Y Axis Scale Installation
1. Install the readerhead mounting bracket to the side of the saddle.
Note: Once the readerhead mounting bracket is installed, position the scale and mounting spar
assembly in position in order to determine the amount of spacers needed for the mounting spar. Also
ensure that the scale is long enough for the saddle travel.
2. Transfer the mounting spar holes to the saddle and mount it.
Note: the mounting spar must be parallel to the Y-axis travel within .005” end to end both horizontally
and vertically. Use spacers and shims as necessary.
3. Slide the scale into the mounting spar and fasten.
Note: the rest of the installation is the same as for the X-axis, Steps 5 through 7.

7.9 System Interconnection
7.9.1 ProtoTRAK SMX Basic System Configuration
See Figure 15 and 16 for all system cable connections.
7.9.2 Cable Routing
Tips for routing the cables on the machine.
•
Before tying up cables, it is a good idea to position them loosely, complete the system
interconnection and ensure that all the cables are plugged in correctly, and that the
system is responding properly.
•
Make sure that no motor cable is tied up next to a power line.
•
Position the table all the way to the left and the saddle all the way forward before
securing the X motor cables.
•
Ensure the knee travel is not restricted.
•
Do not bend umbilical cables. Coil up in a minimum of a 6” diameter.

Note: Various components on Figure 67 have multiple balloons due to these parts varying on
different machines.
Note: The overall strategy is:


The position locator (9), and the hex head screw (18) align the baseplate side to
side.
The leveling nuts (17) align the baseplate front to back.
2. Replace the machine’s head bolts with the Jackscrew nuts (items 12 through 16) on the
right side. Replace the machine’s head bolts with the socket head couplers on the left
side. Items 12 through 16 vary depending on the type of head the kit is being installed
on.
3. Tighten these incrementally to 50 ft/lb. or the mill manufacturer’s spec for the head
bolts.
4. Install the fork on the quill. Tighten to 25 ft/lb. Use locktite, a lockwasher and the
setscrews provided. The forks vary from kit to kit.
Caution!
Do not over tighten the bolt; this may damage the bolt, the quill threads or
deform the quill.
Note: The fork must move smoothly in the slot, otherwise it will have to be modified.
5. Install the position locator (Item 9) where the feed control was located.
6. Install the leveling nuts on the position locator and the jackscrew nuts.
7. Install the base plate with the hex head screw (Item 18) through the hole where the
threaded rod used to be. Use shim between the block and baseplate if necessary.
Note: for shipping, the ball screw and covers are mounted to the base plate. Remove them
before installing the base plate.
8. Install the baseplate with the nut and washers as shown. Use the leveling nuts to
align the baseplate to the travel of the quill front to back. Also, align the baseplate
side to side by placing the level on the right edge of the baseplate and comparing it
to the extended quill. Tighten the nuts to 25 - 35 ft/lb.
Note: The baseplate must be parallel to the travel of the quill for the assembly to work
properly. Use a bubble level on the quill to compare it to the front and side of the base plate.
Check the alignment frequently, especially after installing and tightening the 1/2 - 13 x 1 1/2”
socket screws (Item 30).

8.2 Installation of the Ball Screw
1. Install the ball screw assembly as shown in Figure 67. Run the quill up and down
over its full travel at each step to ensure that there is no binding. Adjust as necessary.
You can mount a dial indicator on the top of the table, locating off the ballscrew. Move
the knee up and down and tram in the ballscrew from front to back with the leveling
nuts.
Note: Loosely install the ball screw at first, and then attach the fork with the quill near the top of
its travel.
Caution!
Binding in the quill travel will impair system performance and may
damage the ball screw assembly.

8.3 Installation of the Motor and Remaining Components
See figure 67 & 68
1. Install the motor mounting bracket to the top of the base plate.
2. Install the motor to this bracket. Install the belt between the pulleys and tension it
by sliding the motor away from the head. Tighten the 4 screws that hold the motor
down.
3. Install the limit switch brackets that hold the upper and lower quill limit switches in
place. Manually move the ballscrew up until you reach a hard stop. Now move the
ballscrew down 1 turn of the ballscrew and set the upper limit switch. The brackets
are slotted to allow up and down adjustment. Move the ballscrew down to the
bottom of its travel and once again turn the ballscrew 1 turn and set the lower limit
switch. In other words, the limit switch should trip about 0.200” from the top and
bottom of travel.
4. The limit switch cable plugs into the digital I/O port on the pendant for non-spindle
control machines. For spindle control mills, the limit switch cable plugs into the
digital I/O port on the spindle control electrics box
5. Temporarily install the Z electronic handwheel to the right side of the baseplate with
2 socket head cap screws. The Z electronic handwheel plugs into the Z-axis
secondary feedback port on the cable breakout box.
6. Power up the control and verify the Z electronic handwheel works.
7. Verify the locations of the switches are set correctly to prevent a hard crash when
the machine is moving at maximum rapid speed. Adjust switches as necessary.
8. Remove the Z electronic handwheel and install the covers and then re-mount the
Z electronic handwheel.
See Figure 68-1 for an illustration of the ballscrew assembly.

Lagun Z Axis Cutout
The ProtoTRAK SMX3 installation for the Lagun FTV2 requires the following material to be
removed from the box that holds the Lagun nameplate.
Figure 69
Unfortunately, there is not a really good way to do this. Your choices are:
•
•
•
Have the head machined
Use a hacksaw
Drill a series of holes and use a wrench to break away pieces (our favorite)
The good news is that the resulting mess will be completely covered with the Z-axis
assembly.

9.3 Replacements
9.3.1 Exchange Program
SWI keeps in stock the major subassemblies required to resolve service problems. With
very few exceptions, the part needed to resolve any given service problem is on the shelf
and ready to ship.
A little bit of troubleshooting on your part means that we can get the right part to you
fast.
After replacing the failed unit with the replacement unit, simply put the failed unit in the
same box that the replacement part came in and ship it back to us via UPS ground
service.
This unique Exchange program gives our customers access to re-built “like-new”
subassemblies that have been brought up to current design revisions and go through the
same QC procedures as our new products. These high-quality replacement units are
available at a fraction of the price of a new subassembly.
9.3.2 Return Authorization (RA) Number
All shipments of replacement parts are accomplished through our Return Authorization
(RA) system. At the same time the CSR is diagnosing the problem and ordering the part,
they will issue an RA number that will allow us to efficiently process the return part.

Disclaimers of Warranties
•
This warranty is expressly in lieu of any other warranties, express or implied, including any implied
warranty of merchantability or fitness for a particular purpose, and of any other obligations or
liability on the part of SWI (or any producing entity, if different).
•
Warranty repairs/exchanges do not cover incidental costs such as installation, labor, freight, etc.
•
SWI is not responsible for consequential damages from use or misuse of any of its products.
•
TRAK products are precision mechanical/electromechanical measurement systems and must be
given the reasonable care that these types of instruments require:
•
Replacement of chip scrapers and wipers is the responsibility of the customer. Consequently, the
warranty does not apply if chips have been allowed to enter the mechanism.
•
Accidental damage, beyond the control of SWI, is not covered by the warranty. Thus, the warranty
does not apply if an instrument has been abused, dropped, hit, disassembled or opened.
•
Improper installation by or at the direction of the customer in such a way that the product
consequently fails, is considered to be beyond the control of the manufacturer and outside the
scope of the warranty.
